What else can I help you with?
Which one is a chemical change-eletrolysis of water or sodium chloride exposed in sunlight?
The electrolysis of water is a chemical change because it breaks down water molecules into hydrogen and oxygen gas. On the other hand, sodium chloride exposed to sunlight is a physical change as it may undergo phase changes, but the chemical composition remains the same.
Is dissolving sodium carbonate a chemical change?
Dissolving sodium carbonate in water is a physical change, not a chemical change. This is because the chemical composition of sodium carbonate remains the same before and after dissolving.
Can sodium be decomposed by a chemical change?
No. Sodium is an element and elements cannot be broken down (decomposed) by a chemical change.
What is the chemical equation of the reaction of litmus paper to sodium chloride?
Litmus paper is a mixture of dyes that change color depending on the acidity or alkalinity of a solution. When exposed to sodium chloride, which is a neutral salt, litmus paper does not undergo a chemical reaction. It remains unchanged in the presence of sodium chloride.
Is adding sodium to water a chemical change?
Yea it is a chemical change. The Sodium reacts with water in a chemical reaction in which the sodium displaces the hydrogen in the water, creating sodium oxide and hydrogen gas. The heat from the reaction ignites the hydrogen, which creates the explosion.

Is sodium a physical or chemical change?
Sodium is a chemical element, not a change.
What are examples of solids in a chemical change?
Examples of solids in a chemical change include baking soda (sodium bicarbonate) turning into carbon dioxide gas and solid copper turning into copper sulfate solution when reacting with sulfuric acid.
Is sodium and chlorine a physical change or a chemical change?
chemical
What is the chemical change of water?
The chemical reaction of water with sodium is a chemical change.
Is dissolving sodium carbonate a chemical change?
Dissolving sodium carbonate in water is a physical change, not a chemical change. This is because the chemical composition of sodium carbonate remains the same before and after dissolving.
Why sodium carbonate is not a chemical change?
Sodium carbonate is a compound. Until you react it with something, it cant have or be a chemical change.
Is the change between sodium and chlorine a physical change or chemical?
chemical
Is sodium can react with water a chemical change?
The reaction of sodium and water is considered to be a chemical change.
Can sodium be decomposed by a chemical change?
No. Sodium is an element and elements cannot be broken down (decomposed) by a chemical change.
